Measurement Computing PCI-DAS1602/12 12-Bit Analog I/O and Multifunction PCI Card

The Measurement Computing PCI-DAS1602/12 is a multifunction data acquisition and control card for the PCI bus, delivering 12-bit analog I/O, digital I/O, and counter functionality in a single plug-and-play board. It eliminates manual configuration entirely—all addressing and interrupt routing are software-controlled. The card accommodates laboratory data collection, instrumentation, production testing, and industrial process monitoring without requiring jumper or switch setup.
